摘　　要：运用三维录像解析技术,对河北省男子排球运动员跳发球的起跳阶段和空中击球阶段进行了分析和研究,结果发现:①在挥臂击球时,腰腹收缩力量小;击球点低,右肘关节伸展幅度小;②与优秀运动员击球时右手瞬时加速度的差距较大,指掌关节速度利用率小,击球效果不理想;③跳发球的最高球速与优秀运动员存在较大差距。并针对上述情况提出了改进建议。This paper analyzed jump servings in take-off stage and ball-hitting stage through the three dimensional video analysis technology,findings： 1） while wielding the arm to hit a ball,contraction of Lumbar abdomen muscle is small;centre of percussion is low,the right elbow extension scope is small;2） there is great difference in transient acceleration of the right hand compared with top athletes,due to the low utility rate of speed of the fingers and the palm,ball-hitting is not ideal;3）there is great difference in highest speed of jump serving compared with top athletes.Advice was given accordingly.
